Horse rears when being led?

What I would do is get a long lead with a stud chain, perhaps a longe line. Handle her like normal, putting the stud chain over her nose. Be sure you do not have the longe line wrapped around your hand. Lead her like normal, and if she doesn't misbehave, then all is good. If she does rear, jerk her hard, and keep jerking, short quick jerks until she comes down, then keep jerking and make her run backwards. Roar, growl and shout at her. Make her think her world is coming to an end. When YOU think she has had enough, stop, and walk her again, just as if nothing happened. If she rears again, same reaction from you. Consistency is key.

What you are doing is impressing on her that the rearing is WRONG, and making a severe enough punishment that it is not worth it to rear again.

Cracking an egg over her head? Hmm, never heard of that method before, but it's a funny mental image!

Anyways, do you use a chain on her already? I hate to suggest it, but if you're not using one, I'd suggest trying it and giving a yank when she goes up.

Another option I've had success with (although the problem was bolting while being led, not rearing) was just repetitiveness. I'd take the horse out of her stall and lead her towards the pasture. The minute she bolted towards it, I'd pull her head sharply back my direction and make a loop back into her stall. I'd release her into her stall, recatch her, and repeat the process until she stopped bolting. Once she stopped, then I let her go out to the pasture as a reward. It took about 2 hours the first day, but now (a month later) she only bolts off maybe once a week.

I'd try the latter if it's safe. If not, do you have a trainer you could work with on the issue?

After the edit: The pent up energy could be a cause, especially if she only started up once you stopped riding. I'd be prepared to deal with it even after you start riding, though. Maybe you'll be pleasantly surprised!

The most dangerous horse in the world is one that rears, they have killed and maimed a lot of people, it is also one of the hardest things to stop and takes a lot of patience and careful training to teach them to stop. I have stopped many from rearing, only had one I could not stop and I advised the owner to sell him which he did, the man that bought him is now in a wheel chair from a broken back because he thought he could stop him. There are a few that will never stop rearing because it is a natural fight stance for horse who can not flee from what they think is danger. You should find some one who deals with problematic horses and send the horse to them.

Well first of all stop playing effin tag with her. What do you think that does? So yes. It may be over feeding and under working. But you hit her after she calmed down and was grazing? What did that prove? You know, just read another book about joining up. It's not worth my time.

Hmmmm vet
